The attached script, when run by an unprivileged user will take my system down within a few minutes. It seems to be some sort of VM corruption. Symptoms are that after processing a few hundred ports, the spawned make(1) (or sh(1) or uname(1) or possibly others) start to die by SEGV. The perl process bombs out, and then after a short hiatus the system panics and reboots -- the message 'vm_page_remove()' is typical, but I've also seen some other ones. If you leap in between the perl script dying and the system crashing, attempting to run one of the programs that crashed, you get a nasty message from /usr/libexec/ld-elf.so.1 >How-To-Repeat: On a system with perl-5.8.5 installed and with a full ports tree: Unpack the attached portindex.uu, untar etc. % cd portindex % ./portindex >/tmp/INDEX and wait...
